Atraumatic splenic rupture in the course of a pneumonia with Streptococcus pneumoniae. Case report and literature review.

Atraumatic splenic ruptures in the course of infectious diseases are rare but have been reported. Various germs of viruses can be at the origin of such rupture. The more often quoted viral disease is infectious mononucleosis. The more frequently involved bacteria are Streptococcus non pneumoniae, Pseudomonas, staphylococci and Clostridium. Rupture mechanism is not clearly elucidated; it can be connected with sepsis diffusion at spleen level via haematogenic way and consequently splenomegaly. Splenic rupture following septicaemia does not always entail major splenomegaly nor abscess formation but the attack of the splenic tissue itself is sometimes sufficient to bring about the rupture. The present case of atraumatic splenic rupture on spleen sepsis, no abscess, starting from a pulmonar infection with Streptococcus pneumoniae is, to our knowledge, the first case reported in literature.SCOPUS: re.j
